General Aptitude- Ratio (Numerical Ability)

RATIO

- Ratio of two terms 'a' and 'b' is denoted as a:b (read as 'a is to b') and it is measured by a/b.

- The ratio cannot be formed until the numbers are expressed in the same units.

- A ratio compares two numbers.

- Ratio remains unaltered when neumerator and denominator are multiplied or divided by same number.

e.g., a:b = a/b = (a*m)/(b*m) = (a/m)/(b/m)
